“…2 % distance) in spite of the large geographical separation. Such a close relationship is also found for Clarias gariepinus populations from both regions and can be explained by the historical connection of the Nile system and West African basins which is currently lost because of climate changes (Trapani, 2008). This shows a common phylogeographical pattern for host and parasites, consistent with the savanna belt formation around the central African tropical forest shaped by Pleistocene glaciations (Hewitt, 2004), which influenced many of Africa's fauna and flora (Trauth et al 2009).…”

“…The occurrence of the hybrids found in Lake Turkana (Kenya) could be explained by the fact that although only C. gariepinus is predominant in the lake, fossils of Heterobranchus sp. have been found (Trapani, 2008), which proves a historical connection with the Nile system (Goudie, 2005) where the latter fish species still occurs today (see also below).…”

Parasite hybridization in African Macrogyrodactylus spp. (Monogenea, Platyhelminthes) signals historical host distribution

Macrogyrodactylus spp. from the gills of Clarias gariepinus in Zimbabwe and Kenya, and C. anguillaris in Senegal were identified using haptoral sclerite morphology and by sequencing the nuclear ribosomal DNA internal transcribed spacers (ITS) 1 and 2, partial 18S and the complete 5.8S rRNA gene. A molecular phylogeny was constructed using all sequenced Macrogyrodactylus species to date. Based on morphology, Macrogyrodactylus congolensis, M. heterobranchii, M. clarii, and M. karibae were identified, with one specimen from Zimbabwe displaying morphological features that were intermediate between M. heterobranchii and M. clarii. In the intermediate form, the partial 18S and ITS1 sequence was identical to that of M. clarii while the remaining ITS1 and complete ITS2 region was almost identical to M. heterobranchii as was the partial cox1 fragment, thus strongly suggesting a hybrid origin. At present, the catfish host of M. heterobranchii and M. clarii do not co-occur in southern Zimbabwe; this hybridization event is therefore proof of historical sympatry of both fish species.

“…Cephalophus and Hylochoerus live in forest environments where the vegetation cover is often dense and there is a regular supply of water. This conclusion is also indicated by the abundance of fossil fish (Trapani, 2008) and water birds (Louchart, 2008) recovered from the Kibish deposits. Mammalian taxa such as Thryonomys, diverse species of tragelaphines, and reduncines also suggest a more closed habitat, one with tall grasses and abundant standing water.…”

a b s t r a c tThe Kibish faunal remains are useful for reconstructing the habitat of the earliest documented Homo sapiens and for understanding the community within which early modern humans existed. A diverse assemblage of large mammals, including many species of bovids, suids, and equids, has been recovered from the Kibish Formation. There are no extinct large mammals represented in the fossil assemblage, and the overall taxonomic composition of the fossil fauna is similar to the modern-day wildlife community living near the Omo River. The fossil faunal assemblage shows a paucity of arboreal primates, and carnivore species are rare. However, the faunal sample includes possible Cephalophus (duiker) remains and Hylochoerus meinertzhageni (giant forest hog), taxa that are extremely rare in the African fossil record, and both indicate more closed habitats. Comparative analyses of the Kibish faunal remains using the ecological-diversity approach document close associations with edaphic grassland and woodland vegetation types. These vegetation forms are similar to current habitats surrounding the Omo River.

“…Their conical shape, which ends distally in an extremely sharp free end, also forms an effective defence mechanism (Claes et al, 2013). The spine of C. carpio additionally possesses recurved serrations that are located on the caudal aspect of the distal third of the spine, similar to spines of Siluriformes (Trapani, 2008;Souza-Shibatta et al, 2013;Vanscoy et al, 2015), several fishes from the Tetraodontiformes and Gasterosteiformes (Bannikov & Tyler, 2006) and spines in the dorsal fin of some shark species (Maisey, 1979). Although the function of these serrations is not entirely clear, the most reasonable speculation is that they are also part of a defence mechanism (Maisey, 1979), injuring attacking predators and allowing the prey to escape (Alexander, 1981).…”

Structure, composition, mechanics and growth of spines of the dorsal fin of blue tilapia Oreochromis aureus and common carp Cyprinus carpio

The structural, compositional and mechanical properties of the spines of the dorsal fin in mature anosteocytic blue tilapia Oreochromis aureus and osteocytic common carp Cyprinus carpio are described, as well as their temporal growth pattern and regenerative capacities. The three-dimensional architecture of both spines, from macro to sub-micron levels, is shown to be axially oriented and therefore highly anisotropic and the spines of both species are able to regenerate after partial amputation.
